Anyone else having problems with the 4.1.2 update for SGS3 for Sprint? I got the OTA update about 3 weeks ago or so, everything went smooth. I didnt really look up what the update added or fixed at the time, then my sister who has the same phone and carrier calls me up and asks me if I got the new Multi-window feature since the update. Come to find out my update for the 4.1.2 is running on my phone, but I dont have any of the features that are supposed to come with it. Went it to Sprint, they said its a Samsung problem and to contact them. Contacted Samsung, they say its a Sprint problem and to contact them. Go figure.. Ive downloaded Kies and tried doing a manual update of the firmware, but it just tells me that my current firmware is not supported to receive firmware updates over Kies. Yes Ive uninstalled, reinstalled, rebooted, cleared cache, rebooted phone. Anyone else have this problem or have any ideas to troubleshoot?
